One pillar to reach the agroecological transition refers to the ‘integrated management of animal health’, an approach through more preventive practices. Innovations exist to improve this management: new technologies (robotics, sensors), the use of alternative medicine (homeopathic, essential oils) and the reduction of the farming system intensity. Our goal is to explore the links between the combination of these three types of health management practices, Livestock Farming System (LFS) consistency and various parameters of work. We surveyed nine dairy farms in Western France selected for their diversity: milk production, workcell size, number of cows/labour unit. Four farms are using a milking robot to decrease their routine work duration but two of them spend specific time to analyse and detect health issues at an early stage. Six farms use sensors to improve their results and to increase their free time (automatic heifers monitoring). The ones who do not use sensors (n=3) are smaller farms and have less cows per labour unit. They find sensors useless and in opposition with the breeders’ role of animal caretaker. The use of alternative medicine is frequent in our sample: Six followed trainings on the use of alternative medicine but four use it as a preventive medicine and three as a curative one. There is no evident link with the cows productivity or the number of cows per labour unit. It appears more as a personal approach, notably from spouses who have often the role of animal nurse in the workforce. The ones using it as a curative medicine tested the products step by step to be confident: they followed trainings years ago. The others followed their training only a few months ago (n=3) and still test it on their herd only in a preventive way. Several work dimensions are evoked in this exploration: workload and robotization, professional identity (meaning of work, digitalization of the data-decision system, gender), labour organization (division between workers, workforce communication). These first results lead us to deepen our understanding on the interactions between the LFS components (health management, work, LFS operation and performances).
